The study aimed to determine the influencing factors and their impact levels on residential land prices. The research investigated 241 officials, real estate investors, appraisers, and real estate brokers on factors affecting residential land prices. Research results have shown 13 groups with 45 factors affecting the price of residential land. The impact rates of the factor groups range from 1.43% to 23.65%. The COVID-19 pandemic factor group has the strongest impact on land prices, followed by other factor groups, including upgrading administrative units; formulation and implementation of the planning; real estate market; financial – economics; credit; real estate brokerage; infrastructure; location of the land parcel; particular factors; juridical factors; environment and social security. To harmonize the interests of the State, investors, and land users when valuing land, it is necessary to pay attention to the factors that strongly impact land prices first, and then the smaller ones.
